Abstract

The study describes the synthesis of Sodium Alginate Graphene-Oxide Silver Composite Thin Film for photocatalytic activity of methylene blue. The composite thin film then characterized by using UV-visible absorption spectra (UV-Vis), Fourier transform infrared Spectroscopy (FTIR) and X-ray Diffraction (XRD) analysis. The FTIR shows the functional group contained in the composite thin film and proved that sodium alginate and Ag particles were successfully composited on the rGO sheet. Sodium alginate GOAg composite thin film also shows its high absorbance for photocatalytic activity to degrade methylene blue under sunlight. This is due to the presence of rGO in the composite as it prevents the aggregation between particles thus increase the surface area. Furthermore, the recombination rate of electron – hole pair also one of the factor that affect the photocatalytic reaction. The sodium alginate GOAg composite thin proved that it has huge potential in the water treatment industry.
